Remove obsolete -D_REENTRANT requirement, ask for thread support

Remove the obsolete requirement that libraries be built with
-D_REENTRANT, as this no longer does anything significant in current
versions of glibc.  Instead, state directly that libraries should be
built with threading support and to be thread-safe if this is
supported.
